Yeah, those are good thoughts. I haven't actually heard sound from
the PC yet (it's new, and didn't come with an OS), so plan to load
up a few live CDs to check whether things work better there, and to
more closely rule out hardward issues. I have tried plugging my
speakers into everywhere, though, so think it's unlikely to be the
issue here (and checked that audio was enabled in my bios).

As alsamixer and related applications all don't start due to an
error at the moment I can't do this, and it implies that it's more
than just a little configuration thing sadly.

I really hope I don't find out that it's something stupid like that
in this case! Doesn't seem to be, I think.
Thanks.
